Agriculture in Singapore became heavily reduced as early as 1987. In that year, there were officially 2,075 farms in the country, covering an area of 2,037 hectares (5,030 acres), an average of less than 1 hectare (2.5 acres) per farm. [2] Before modernised development, Orchard Road was a stretch of agricultural orchards.
Puddling is the tillage of rice paddies while flooded, an ancient practice that is used to prepare for rice cultivation.
